Ensure 'SUPER' is Not Granted to Non-Administrative Users

HighLevel 1Automatedoceanbase

Description

The SUPER privilege determines whether a user can perform certain powerful administrative functions, including terminating user sessions via the KILL command, modifying global MySQL variables using SET GLOBAL, and executing various commands related to replication and logging. Runs obclient with the connection options in OB_CONN (default "-h127.0.0.1 -P2881 -uroot@sys"); point it at the MySQL-mode tenant being assessed and supply the password via OB_CONN (-p...) or a [client] section in ~/.my.cnf. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Passes when no non-root grantee holds SUPER.
